A turn on power move. When a girl is love with a guy so much, but none of them has amitted it, (or the guy doesn't know he's in love with her), the girl takes the boy and kisses the guy, leaving him with a suprised look.

In Spectacular Spider Tv Series, Gwen Stacey was going down the stairs of Peter Parker/Spiderman's steps (after Thanksgiving, and his Aunt May just came back from the Hospital), she walked back up the stairs and surprise kissed Peter. Leaving him with a dumbass surprissed look. Venom's voice said in his mind "We know who you love the most."
in Star Wars: The Force Unleashed, Juno Eclispe, fearing she would never see Galen Marek again (Vader's former apprentice), who was going to confront Vader, she kissed him, he showed his suprised by raising his arms half way in the air, then continued in the kiss.
George Lopez is suprise kissed by his wife's Sister in "A Kiss is Just a Kiss."
